Iteration
What is Iteration in Product Design?
Iteration in product design is the process of repeatedly refining and improving a product based on feedback, testing, and evaluation. It involves making incremental changes to design elements to enhance usability, functionality, and user experience.
Synonyms: repetition, refinement, revising, cycling, improvement process

Why Iteration is Important in Product Design
Iteration allows designers to continuously improve a product by learning from real user feedback and testing results. This process helps identify and fix issues early, reduce risks, and create a product that better meets user needs and business goals.
How Iteration is Used in Product Design
Designers create prototypes or initial versions of a product and then test them with users. Based on the feedback and data collected, they make adjustments and improvements. This cycle repeats multiple times until the product reaches a satisfactory level of quality and usability.
Examples of Iteration in Product Design
- Updating a mobile app interface after user testing reveals navigation difficulties.
- Refining a website layout based on A/B testing results.
- Enhancing a physical product's ergonomics after prototype trials.
Frequently Asked Questions
- What is the main goal of iteration in product design? The main goal is to improve the product continuously to better satisfy user needs and business objectives.
- How many iterations are typical in product design? The number varies depending on the project complexity, but multiple iterations are common to ensure quality.
- Is iteration only about fixing problems? No, iteration also involves enhancing features and adding new improvements based on user feedback.
